Add CI relationships

Discovery automatically maps the dependencies between CIs that it finds in the network
and assigns the appropriate type to each relationship.

Before you begin

Role required: Admin

About this task

Administrators can add dependencies manually and to define the appropriate
relationship type between new configuration items based on lists of suggested
relationships.

The best practice when adding application dependencies to a configuration item is to
avoid the use of the Runs on/Runs and Hosted on/Hosts types. When a configuration
item is deleted, any upstream CIs with a relationship type of Runs on or Hosted on
is deleted as well. In some cases, manually added CIs might have other important
dependencies that are adversely affected by the cascade deletion triggered by these
two relationship types.

To add a dependency:

Procedure

In a CI record, click the + icon in the
Related Items toolbar.

Select the appropriate relationship type from the list at the top of the
page.

Create and run an appropriate filter to make the CI visible in the list of
available CIs.

Move the CI from the list of available CIs to the dependent list.

Click Apply to.

Example

An example of the importance of selecting the proper relationship type is when the
Business Service dependency, PeopleSoft CRM, is added to the sannnm-01 virtual server in
the following diagram. If PeopleSoft CRM is added with a relationship type of Depends
on, it is protected from the cascade delete triggered by the deletion of the Windows server sannnm-01. This is
important because PeopleSoft CRM has dependencies to other servers and must not be
deleted.
